Our GTREP repository database for CA Test Data Manager is currently running on Oracle 12, and our DBA would like to upgrade to Oracle 19c. Does TDM support Oracle 19c?
Release : 4.9.1
Although Oracle 19c has not been officially certified, with TDM 4.9.1, we do support the use of Oracle 19c with the gtrep repository database, or as a supported source database.
As long as you are on a 4.9.1 release, you should be fine upgrading your Oracle database from 12 to 19c.
